Optical properties of 1-D active fibonacci quasicrystals

Quasicrystals based on the excitonic resonances of GaAs/AlGaAs quantum wells were grown with spacings that satisfy a Fibonacci sequence. Linear and nonlinear reflectivity and photoluminescence measurements were performed, agreeing quite well with theory.
